This can be so very complicated. Relationships are complex and add the element of money and you may have a recipe for disaster. Your teacher whether it be for dance, piano, or political science has the responsibility to teach you in a safe enviornment where he or she does not exploit your eagerness to please or to learn. Many times people (women especially) take dance lessons becasue they are bored or lonely and are looking for something to add to their lives. Often their children are grown or they don't have children and have a lot of disposable time. Teachers walk a fine line between being a friendly companion for an hour or two in the studio and becoming over involved with someone who pays them to spend time with them. I've seen instructors become far too involved with their students, date them, hook them up with dates, go drinking with them, call everyday etc. And I have yet to see any of these situations end well. I am not saying that the relationships are formed out of malice. Just the opposite. It is human nature to want to spend more time with someone you like. I think however more instructors need classes on professional ethics. We have a responsibility to our students and we breach that when we become too involved. If your relationship is destined to really grow, I suggest that the teacher help his/her student find a new instructor so as to eliminate the ethical concerns one would have about the situation.
